So, back to mantel clock demolition! Here you are, with a beautiful coiled mantel clock movement, uncertain about what to do with it. Don’t be scared, power tools are tons of fun to play, er, work with! The Dremel is a relatively safe power tool to work with, and unless you somehow held the cutting tool to your finger, all appendages should be safe.
1. The first thing you should do when cutting open a clock movement is find a good place to work. You want to work outside if you can, but a cleared solid table in a well insulated room can work.
3. Put on goggle, this is non negotiable, when opening a clock movement, springs, gears and parts can go everywhere. You can choose to where gloves and a gas filter if you want, it depends on you.
4. One thing to remember about the Dremel is that it is delecate, you can’t cut open a large movement like the ones found in mantel clocks in one sitting, the Dremel with over heat and then you will need a new fan. Be sure to have plenty of time to allow your Dremel to rest.
5. Now you are ready to cut! Place the cutting tool on the dremel (this was explained in a past post). The movement is two pieces, held together by solid brass bolts, that no bolt cutter will be able to cut through, thus the Dremel. Place you gloved hand over the edge of the movement where the springs stick out to prevent them from popping and place the other part of the piece upright on the table.
6. Make sure you have a solid hold on the movement and begin cutting slowly through the closest bolt, pausing frequently to allow your dremel to cool. Be careful as you continue to the next bolt as your spirals will begin to loosen and try to pop out.
7. Once you have all the large bolts cut through you can move to the small parts, slowly cutting them either with the Dremel or a bolt cutter, until the two large brass pieces pop apart and you can open the movement completely.
8. Now the movement is cracked open and you can get to the goodies inside!
Look for my next post on how to clear and cut gears for decoration and jewelery making.
If you have done this properly you should have a piece that looks like this!
